General Vacuum Pumps - General, Physical, Functional And Interface Description

Question 1

Dead End

Answer 1

The lowest possible pressure obtainable using given vacuum pump, with the suction valve closed

Question 2

Solenoid Valve (SV-1) Vacuum Pump Safety Feature

Answer 2

Closes when the pump motor turns off or during a power loss to prevent back leakage through the pump

Question 3

Vacuum Pump Power Requirements

Answer 3

3/4 HP Motor
440 VAC
3 Phase
60 Hz

Question 4

Pump Assembly Construction Features

Answer 4

Aired cooled, rotary piston, high-vacuum pump consisting of two rotary piston pumping stages

Question 5

Vacuum Pump Discharge Valve

Answer 5

Spring loaded valve consisting:
2 Plates 
2 Springs 
2 Bolts 
Prevents backflow of gas after discharge

Question 6

Vacuum Pump Center Wall Seal

Answer 6

Made of Viton

Prevents equalization of pressure between high Vacuum and backing stages

Question 7

Vacuum Pump Suction Valve V-14

Answer 7

Diaphragm type

Isolated annulus from solenoid valve and vacuum pump

Question 8

Vacuum Pump Solenoid Valve SV-1

Answer 8

Diaphragm type

Protects the annulus from backflow and maintains vacuum

Question 9

Vacuum Pump Valve V-22

Answer 9

Below seal type

Used to depressurize annulus space

Question 10

Vacuum Pump Functional Operation

Answer 10

The oil forms a vacuum-tight seal between the piston and the cylinder wall, as well as between all of the working components

Question 11

Vacuum Pump Gas Ballast Valve

Answer 11

Angle type valve

Prevents condensation in the pump lubricant, reduces valve noise and controls the vapor handling capacity
